# About DIH

The OpenText Distributed Index Handler (DIH) is a distribution server that distributes index actions to Content components. Distribution enables you to scale your system in a linear manner, increasing the speed of index actions and saving processing time. Distributing the index between multiple copies of the Content component can also ensure uninterrupted service if a Content component fails.

The setup of your Content component is independent of the DIH, because they are architecturally unaware of it.

The DIH can index unstructured, semi-structured, or structured data into the connected Content components. You can aggregate this data from any type of repository by using Connectors. Connectors import the data into IDX file format (unless the data is in XML format, which Content also accepts) and passes it on to the DIH.

In addition to indexing data into the connected Content components, the DIH can also forward administrative index actions to its child Content components, for example to:

- activate Content configuration changes.

- delete content from the Content index.

- create new Content databases.

- expire documents.

- compact Content indexes.

- change field values in Content documents.

- back up Content.

- initialize Content.

- validate the subindexes in a Content index.

For details of all the index actions that the DIH accepts, refer to the Distributed Index Handler Reference.
